An automatic short length wire shape generation and strapping and method of fabricating such wires is provided. 35>\u0394Htr accompanying a transition at about 240\xb0 C. Thus, for locking the rotational shaft in a fixed state, an operator grips and turns the rotatable ring with one hand to engage the slide plates with the coupling portions by the slider shift mechanism. An actuation mechanism causes the third link to move radially outward from the tool for engagement with the inner wall.
